Rotoplasmonic Excitations in the Electron Gas

Abstract

By means of group theory we show that collective excitations of the electron gas which carry certain angular momentum in addition to the linear momentum exist. The energy E q m of such excitations has been calculated. For q tending to zero E q m goes to E o q , i.e. it coincides with the usual plasmon energy.
